The mayor this week dropped his re-election bid and endorsed his former rival.

And if Foster has any chance of accomplishing their mutual goal of stopping Joseph Ganim’s comeback, she needs Finch backers to follow his lead, particularly Hispanics like Casco.

But as of Thursday some of those allies — Casco included — were either still wary of Foster or weighing their options.

“I was there (at the rally) because I was with Bill Finch,” Casco said. “But that doesn’t mean I support her 100 percent. Not yet.”

Ganim, an ex-mayor who was convicted in 2003 of public corruption and served seven years in prison, defeated both Finch and Foster in the Sept. 16 Democratic primary with help from black voters.

Finch has traditionally performed well in Hispanic neighborhoods.

Councilwoman Lydia Martinez ran on Finch’s primary ticket for town clerk and won. Yet she was noticeably absent from not only Foster’s rally, but Tuesday’s endorsement announcement when supporters of team Finch and team Foster came together in a show of anti-Ganim of unity.

“I don’t have any problem with Mary-Jane Foster,” said Martinez, noting Foster has been successful in business and, as a vice president at the University of Bridgeport cares about education.

But, Martinez said, she and others want to meet with Foster to ensure she addresses issues in their community and to better understand how this new “fusion” campaign will work with five weeks until Election Day.

“If I’m working with her you know I’m going to work hard for her and recruit other people to work hard for her, too,” Martinez said. But, she added, “if I don’t see things are the way they should be” then Martinez will simply run her own race for town clerk and stay out of the mayoral contest.

“I’m not with Joe Ganim,” Martinez said.

Martinez’s council partner, Milta Feliciano, who also runs Finch’s veterans’ affairs office, and state Rep. Ezequiel Santiago both said they are entering the new mayoral landscape with an open mind.

“Bill (Finch) thinks for Bill and not for me,” Feliciano said. “When we first went into this, Bill asked me for my support and I gave him my support. I didn’t give anybody else my support.”

Santiago said he and some colleagues will be meeting with both Foster and Ganim. He said Finch had the chance to have a heart-to-heart talk with Foster and others deserve the same opportunity.

“I respect Bill and have been with him all the way, but this is a different candidate altogether,” Santiago said.

Councilman Enrique Torres, the Republican Party’s mayoral candidate, said it is becoming clearer that while Foster, who ran in the primary as an outsider, may have decided to partner with one faction of the Democratic machine, “That does not mean it moves the way Bill Finch says.”

Still, it has been less difficult for other Finch allies like Carmen Colon to make the transition.

Colon is influential in her own right and also longtime girlfriend of state Senator-turned-Motor Vehicles Commissioner Andres Ayala.

She was at Foster’s rally Wednesday and issued a passionate plea to elect her mayor, arguing Ganim’s return would be a step backward.

She said Finch has done “an amazing job” and she knows Foster and is confident in her leadership.
